1. var is easier to type and would be basically a universal type.

2. right now is confusing to use.
it might be harder to implement, but it makes code cleaner and 
more readable.

3. I would rather not have to call a function for coroutines to 
create them.
its alot easier to just yield out of a function. of course if 
this slows the language down it would be bad.

I think the language should auto detect if a yield is used and 
execute and store a coroutine until it is finished.
